An unnamed protagonist (Edward Norton), an "everyman" who is discontented with his white-collar job, moves from touring support groups to forming an underground club with a strange soap salesman named Tyler Durden (Brad Pitt)--a club with strict rules where he fights other men who are similarly fed up with their mundane lives. Their perfect partnership frays when Marla (Helena Bonham Carter), a fellow support group crasher, attracts Tyler's attention. Based on the 1996 novel of the same name by Chuck Palahnuck and directed by David Fincher.
